(6) 2-point calibration in case it is difficult to perform 「Zeroing」
In case zeroing is difficult to perform such as measuring the thickness of the film on the rough surface of Blast-steel plates,
a calibration method using 『2 different thicknesses of standard plates』 pinching a thickness of the object is defined as
｢JIS K5600｣ Standard. This calibration method complies to the regulations.
Caution
It is not possible to use both this calibration method and other calibration ones together, or mixing them together.
Should were the methods taken, measuring results could be the wrong values.
